The heterogeneous integration of III-V devices with Si-CMOS on a common Si platform has shown great promise in the new generations of electrical and optical systems for novel applications,such as HEMT or LED with integrated control *** heterogeneous integration,direct wafer bonding(DWB)techniques can overcome the materials and thermal mismatch issues by directly bonding dissimilar materials systems and device structures *** addition,DWB can perform at wafer-level,which eases the requirements for integration alignment and increases the scalability for volume *** this paper,a brief review of the different bonding technologies is *** that,three main DWB techniques of single-,double-and multi-bonding are presented with the demonstrations of various heterogeneous integration ***,the integration challenges,such as micro-defects,surface roughness and bonding yield are discussed in detail.

High-performance GaInP/AlGaInP multi-quantum well light-emitting diodes(LEDs) grown on a low threading dislocation density(TDD) germanium-on-insulator(GOI) substrate have been demonstrated. The low TDD of the GOI substrate is realized through Ge epitaxial growth, wafer bonding, and layer transfer processes on 200 mm wafers. With O_2 annealing, the TDD of the GOI substrate can be reduced to ~1.2 × 10~6 cm^(-2). LEDs fabricated on this GOI substrate exhibit record-high optical output power of 1.3 mW at a 670 nm peak wavelength under 280 mA current injection. This output power level is at least 2 times higher compared to other reports of similar devices on a silicon(Si) substrate without degrading the electrical performance. These results demonstrate great promise for the monolithic integration of visible-band optical sources with Si-based electronic circuitry and realization of high-density RGB(red, green, and blue) micro-LED arrays with control circuitry.

β-兴奋素和生长激素是目前畜牧科学研究的一个热点。1990年夏季举行的美国畜牧科学年会上,有关β-兴奋剂和生长激素的论文就有百篇之多.这两种激素之间有一些相同之处,如都能促进家畜瘦肉生长。也有一些不同之处,如:β-兴奋剂的作用没有畜种的专一性,而生长激素专一性很强;β-兴奋剂可以口服,生长激素只能注射;β-兴奋剂只在育肥期后期短期施用就有效,而生长激素在整个饲养期间都能发生效用;生长激素能促进家畜身体各部分生长,而β-兴奋剂对后躯生长的促进作用很明显.

Large Scale multiple input multiple output(MIMO) systems have recently emerged as a promising technology for 5G *** they have been shown to offer significant performance benefits in theoretical studies,the large scale MIMO transmitters will have to be deployed in the limited physical space of today's base stations(BSs).Accordingly,this paper examines effects of deploying increasing numbers of antennas in fixed physical space,by reducing the antenna *** focus on the resulting performance of large-scale MIMO transmitters using low complexity closed form precoding *** particular,we investigate the combined effect of reducing the distance between the antenna elements with increasing the number of elements in a fixed transmitter *** gives rise to two contradicting phenomena:the reduction of spatial diversity due to reducing the separation between antennas and the increase in transmit diversity by increasing the number of *** quantify this tradeoff,we investigate densely deployed uniform antenna arrays modelled by detailed electromagnetic *** results show the somewhat surprising result that,by reducing the separations between the antennas to significantly less than the transmit wavelength to fit more antennas,the resulting system performance improves.

Increasing Throughput in Nano LC-MS for Proteomics

作者： David W.Neyer Jia eng Siow Remco van Soest kenneth R.Hencken Jason E.Rehm

While peptide separations with nano LC have historically been conducted with fairly long gradient elution and re-equilibration times, the demands for instrumentation that will deliver increased throughput while maintaining the sensitivity benefits of nano ESI has increased. Fast gradient analysis of peptide samples are presented that take advantage of precise gradient control with small volume mixing and low gradient delays. Combined with parallel column approaches, these fast chromatography runs can be used to provide significant increases in sample throughput and data collection. Higher pressure LC operation along with external gradient mixing provide additional tools for further increases in speed, resolving power, and sensitivity to meet the demands of higher throughput experiments in areas such as biomarker analysis and peptide quantification.
